To all whom tm/ay concern.-

Be it known that I, JOSEPH W. HoBsoN, a citizen of the United States,residing at Bayonne, in the county of Hudson and State of New Jersey,have invented a new and useful Ealing-Press, of which the following is aspecification.

This invention relates to presses for baling hay and similar material;and it has for its object to simplify the construction and to improvethe operation of this class of devices.

The present invention consists in the improved construction and novelarrangement and combination of parts, which will be hereinafter fullydescribed and particularly pointed out in the claims. y

In the accompanying drawings has been illustrated a simple and preferredform of embodiment of the invention, it being, however, understood thatno limitation is necessarily made to the precise structural detailstherein exhibited, but that the right is' reserved to any changes,alterations, and modifications to which recourse may be had within thescope of the invention and without departing from the spirit orsacrificing the efficiency of the same.

In said drawings, Figure 1 is a perspective view showing the frame andthe operating mechanism of the improved press, the casing or lining ofthe press having been almost entirely removed for the purpose of betterillustration. Fig. 2 is a perspective view of the press seen from thedirection of the balingchamber and showing all the doors of thebaling-chamber open, but showing the fastening means for the front andtop doors in position. Fig. 3 is a detailed side View of the front endof the press, showing the doors of the baling-chamber shut. Fig. 4 is asectional detail view taken on the line 4 4 in Fig. 3.

Corresponding parts in the several figures are indicated by likecharacters of reference.

The frame of the improved baling-press includes a pair of sills l, whichare disposed parallel to each other at each side of the press, as willbe readily understood, although only one of said sills appears in thedrawings. Suitably connected with said sills are pairs Aof uprights 2,3, 4, and 5, which are suitably spaced. apart, the uprights 2 beingdisposed at the front and the uprights 5 at the rear end, while theuprights 3 and 4 are intermediately disposed. These uprights are spacedand connected at their upper ends by means of longitudinal rods 6 7 andtransverse braces 8 8, constituting a strong and durable frame, asclearly shown in Eig. 1 of the drawings. This frame is provided with alining which constitutes the casing of the press, said lining beingconstructed of lumber of suitable thickness. A portion 9 of said liningextends the entire length of the frame and constitutes the lioor of thepress. The sides and the top, only a portion of which latter has beenshown, are intended to extend between the uprights 3 and 5 to form thetop10 and sides 11 of the press.

The baling-chamber of the improved press is included between the floorof the press, a pair of side doors 12 12, a top door 13, anda front orend door 14, the remaining side of the baling-chamber being formed bythe headblock or follower 15, as will be hereinafter described. The sidedoors 12 12 are hingedly connected with the uprights l3 3 and areadapted to fit between the latter and the front uprights 2 2, as will bereadily understood. Said side doors are'provided with straps 16,projecting at their free edges and constituting stops which when thedoors are closed abut upon the uprights 2. The latter are provided withL-shaped hooks or catches 17, and mounted pivotally at the lower ends ofsaid uprights are levers 18, provided with suitably -disposedwedge-plates 19, adapted when the levers are raised to engage the hooksor catches 17, while the bodies of the levers bear against the stops orstraps 16 of the doors, which latter will thus be retained in closedposition. The-levers will be retained in engaging position by frictionalcontact between the wedge-plates 19 and the hooks or catches 17.

The top door 13 is hingedly connected with the transverse brace 8,connecting the upper ends of the uprights 3 3, and said top door isprovided at its free edge with lugs 20, adapted to engage thecross-brace 8, connecting the closed, its upper edge will engage thecross-V braee 8, connecting the uprights 2, and said door maybe retainedin closed position by means of a bar 24 engaging a pair of keepers 25upon the front uprights 2.Y

The head-block or follower 15 is mounted for longitudinal movement inthe press-box,

and it is supported upon rollers or wheels 26, suitably journaled nearits lower edge. The follower is provided upon its rear side with avertically-disposed brace 27, to the sides of which are secured a pairof spaced push-bars 28, the rear ends of which are preferably supportedby iianged rollers 29 upon a shaft 30, supported by the rear uprights 55, thus enabling the follower and its related parts to be easilyoperated. Upon the upper sides of the push-bars 28 are securedratchet-bars 31, the teeth of which are beveled or inclined in aforw-ard and downward direction.

The rear uprights 5 5 support a shaft 32, carrying pawls or dogs, as 33,which engage the ratchet-bars 31 and act as detents to prevent rearwardmovement of the follower. T designates a toggle composed of a pair oflinks 34'and 35, which are pivotally connected by a pin 36, and thelatter of which, 35, is pivotally supported upon the shaft 32. The frontend of the link 34 has a transverse pin 36a, carrying a pair of trailingpawls 37, the toothed ends of which engage the ratchet-bars 31, as willbe clearly seen in Fig. 1. Suitably' connected with said trailing pawlsare chains or flexible members 38, whereby they may be raised fromengagement with the ratchet-bars, said flexible members being of anysuitable length and extended to any suitable point where they may bereadily laid hold of by the operator.

The bottom of the press-box supports a transverse shaft 39, having atone end a socket 40, in which is fitted a hand-lever 41. The shaft 39has a crank member 42, which is connected, by means of a link 43, withthe pin 36, whereby the links ofthe toggle-joint are pivotallyconnected. Thev proportion and relative arrangement of the parts is suchthat when the shaft 39 is operated by the lever 41 to move the crank 42in an upward direction the pivotally-connected ends of the toggle-klinks 34 and 35 will be elevated and the trailing pawls will be causedlto slide in a rearward direction over the teeth of the ratchetbars 31,the latter being meanwhile prevented from backward movement by the pawlsor detents 33. When the lever is depressed and 'the crank 42 is movedtoward a horizontal position, the pivotally-,connected ends of thetoggle-links will be lowered and the trailing pawls will move in aforward direction, acting upon the ratchet-bars, and consequently movingthe follower forwardly in the direction of the baling-chamber. When thisforward movement takes place, the detents 33 will slide over the teethof the ratchet-bars. v Ashort chain or similar iiexible member 44 may beconnected with the upper end of one of the uprights 5, said chain beingadapted to be detachably connected with the handlever 41 for the purposeof securing the latter in an approximately upright position when thepress is not in use. Suitably-supported hook members 45 are provided,said hook members being adapted to engage chains 46, connected with thefree ends of the trailing pawls 37, which latter may thereby beraisedfrom engagement with the ratchet-bars and supported in inoperativeposition.

By making slight modifications', which are within the skill of theordinary mechanic, the operating mechanism of the press may be changed,so as to enableit to be operated by power instead of by means of thehand-lever 41.

From the foregoing description, taken in connection with the drawingshereto annexed, the operation and advantages of this invention will bereadily understood. Initially the follower is moved rearwardly into thepressbox as far as possible, this being accomplished by first raisingthe trailing pawls from engagement with the ratchet-bars by means of thechains 38, which may be placed temporarily in engagement withsupporting-hooks 45, while the detents 33 are likewise temporarilydisengaged from said ratchet bars. When the follower has been movedrearward to the desired extent, which is accomplished manually bypulling upon the bars 28, the pawls 37 and detents 33 are again placedin engagement with the ratchet-bars, and the front or end door 14 of thebaling-chamber is thrown open, after which the material to be compressedis pitched .into the press-box and baling-chamber. The door 14 is thenclosed and secured by the cross-bar 24, and the operating mechanism ofthe press is then manipulated, thus forcing the follower forwardly inthe direction of the baling-chamber and compressing the material withinthe latter. When the material has become sufiiciently compressed orcondensed, the side doors of the press may be thrown open while the baleis being tied in the usual manner. The front door of the press is thenthrown open to relieve the pressure upon the bale, thus enablingthedetents and pawls to be readily disengaged from the ratchet-bars whilethe follower is being withdrawn, and the bale may then be removed fromthe press. As will be seen, access may be had to the bale from foursides, so that if the bale should become stuck or hung in thebaling-chamber it may be readily freed and ejected.

By the operating mechanism which has been herein described a great powermay be developed with slight initial exertion and the material may becompressed to a great degree of density.

Having thus described the invention, what is claimed is v 1. 1n abaling-press, a frame having posts or uprights, a baling-chamber havingdoors hingedly connected with uprights spaced from the front end of thepress, said doors having stops abutting upon the front uprights,hookshaped catches upon said uprights, and levers connected pivotallywith said uprights and having wedge-plates adapted to engage saidcatches.

2. In a baling-press, a press-box, a balingchamber at the front end ofsaid box, said baling-chamber being provided with an end door, a topdoor, and vertically-hinged side doors, means for securing said doors inaclosed position, a follower movable longitudinally in the press-box andhaving a vertically-disposed brace upon its rear side, pushbarsconnected with and spaced apart by said brace, rotary supporting meansfor the follower and the push-bars, and means for forcing the latterforwardly in the direction of the baling-chamber.

In testimony that I claim the foregoing as my own I have hereto aiixedmy signature in the presence of two witnesses.
